Product details
Overview
71V016SA10BFGI8 from Renesas Electronics is a 64K × 16-bit (1 Mbit) high-speed CMOS static RAM with 10 ns access time, single 3.3 V supply operation, industrial temperature range (–40°C to +85°C), and 48-ball FBGA (BFG48) package. It features LVTTL-compatible bidirectional I/Os, separate upper/lower byte enables (BHE/BLE), and full static asynchronous operation requiring no clocks or refresh - deployed in real-time control buffers, FPGA configuration storage, and legacy bus-based embedded systems.
For engineers reviewing the 71V016SA10BFGI8 datasheet, 71V016SA10BFGI8 pinout, 71V016SA10BFGI8 application, or 71V016SA10BFGI8 equivalent, key selection criteria include its 10 ns read cycle time, industrial-grade reliability, byte-selectable write capability, and compatibility with 3.3 V LVTTL bus interfaces in space-constrained PCB layouts using the 7 × 7 mm BFG48 package.
Technical Context
The 71V016SA10BFGI8 implements fully static asynchronous memory architecture with independent chip select (CS), output enable (OE), write enable (WE), and dual-byte enable (BHE/BLE) controls - enabling word, high-byte, or low-byte read/write operations without external timing logic. Its internal decoders and sense amplifiers support concurrent address decoding and fast data latching with zero wait states.
All I/Os are LVTTL-compatible (VIH = 2.0 V min, VIL = 0.8 V max), and the device draws only 10 µA standby current (ISB1) while maintaining full data retention. The 48-ball BFG48 package uses JEDEC-standard ball map with dedicated VDD/VSS pairs for noise suppression and signal integrity in high-density designs.
Key Specifications

Pinout & Package
71V016SA10BFGI8 is housed in a 48-ball plastic FBGA (BFG48) package per JEDEC MO-245, with 7 × 7 mm body size and 0.8 mm ball pitch. Ball assignment follows standard memory layout optimized for signal integrity and power delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus accepting 0–65,535 row/column locations; fully static - no setup/hold timing required beyond tAS = 0 ns. |
| CS | Chip Select | Active-low enable controlling entire memory array; tACS = 10 ns max ensures fast peripheral selection in multi-chip systems. |
| OE | Output Enable | Active-low control for tri-state output drivers; tOE = 5 ns max enables precise read strobe alignment with CPU or FPGA timing. |
| WE | Write Enable | Active-low write control; supports WE-controlled, CS-controlled, or byte-enable-controlled write cycles per truth table. |
| BHE / BLE | Byte Enable Inputs | Independent high-byte (I/O8–I/O15) and low-byte (I/O0–I/O7) write masking - eliminates need for external byte-lane gating logic. |
| I/O0–I/O15 | Bidirectional Data I/O | 16-bit LVTTL-compliant data bus; internally managed direction control eliminates external transceivers in most applications. |
| VDD / VSS | Power / Ground | Dual VDD (balls A1, E1, G1) and VSS (balls A5, D1, G5) placements reduce IR drop and improve noise immunity. |

FAQ
What is the maximum operating frequency supported by the 71V016SA10BFGI8?
The 71V016SA10BFGI8 does not operate on a clock; it is an asynchronous SRAM. Its 10 ns access time (tAA) and 10 ns cycle time (tRC) support effective bus frequencies up to 100 MHz in zero-wait-state configurations. Timing is governed by address valid setup (tAS = 0 ns) and hold (tWR = 0 ns) parameters, enabling direct interface with high-speed microcontrollers and FPGAs without added wait states.
Does the 71V016SA10BFGI8 require external refresh circuitry?
No, the 71V016SA10BFGI8 is a fully static CMOS SRAM and requires no refresh cycles, clocks, or external timing generators. Its internal latches retain data indefinitely as long as VDD remains within 3.15–3.6 V and temperature stays within –40°C to +85°C. This eliminates refresh-related jitter and simplifies system design compared to DRAM or pseudo-SRAM solutions.
Can the 71V016SA10BFGI8 be used with 5 V tolerant microcontrollers?
No - the 71V016SA10BFGI8 is strictly a 3.3 V LVTTL device with VIH = 2.0 V (min) and VIL = 0.8 V (max). It is not 5 V tolerant. Direct connection to 5 V logic requires level translation. However, it interfaces natively with 3.3 V I/O standards including ARM Cortex-M, Xilinx Artix-7, and Renesas RA series MCUs without voltage translation.
What is the ball pitch and footprint compatibility of the 71V016SA10BFGI8 BFG48 package?
The 71V016SA10BFGI8 uses a 48-ball FBGA (BFG48) package with 0.8 mm ball pitch and 7 × 7 mm body size per JEDEC MO-245. Its ball map is identical to other Renesas 71V016SA variants in BFG48, enabling footprint reuse across speed grades (10/12/15/20 ns) and temperature grades (C/I). PCB land pattern must follow IPC-7351B "BGA48_7X7_P0.80_BALL" recommendations.
How does the byte enable functionality work on the 71V016SA10BFGI8?
The 71V016SA10BFGI8 uses two dedicated inputs - BHE (high byte enable) and BLE (low byte enable) - to selectively activate I/O8–I/O15 or I/O0–I/O7 during write cycles. When only BHE is low (BLE high), only the upper byte is written; when only BLE is low (BHE high), only the lower byte is written. Both low enables full 16-bit word write. This eliminates need for external byte-lane gating logic in mixed-data-width systems.
